"2-Butoxyethanol is frequently found in popular cleaning products. It provides cleaning power and the characteristic odor of Windex and other glass cleaners. It is the main ingredient of many home, commercial and industrial cleaning solutions, such as Simple Green All-Purpose Cleaner."
DQuixote, thank you for posting that information. I make my own homemade cleaning solutions now, use vinegar and water for windows, do my laundry using borax and arm & hammer, and run the dishwasher using vinegar. Sometimes I even use essential oils for cleaning certain things.
Commercial cleaners and scented soaps give me a headache.
